Controllerable Tunzes Advise Needed

[stonecold]

I have a mixed reef with SPS being placed in the middle and upper third of the tank. LPS and Zoanthids are at the bottom. Currently, I have a GenX Mak4 for return thru a 1" Sea Swirl. For internal flow, I am using 2 6045 Tunze streams and 2 Moded MJ with SureFlow kits. I would like to eliminate all 4 power heads and just do 2 Tunzes that are controllable. Dimensions of my tank is 4x3x2 (LxWxH).

Please advise as to which model would best suit my need...used models and new models.

Thank you!

My opinion would be due to the width of the tank my first inclination would almost be to go with 2 6205s as they have a much broader flow pattern but if it is not a heavy SPS tank 2 6105s would likely be just fine. The large foot print can be hard to cover with just two pumps but with the help of the SeaSwirl if it is centrally located it might be a bit easier to get the desired result.

I think 2 6105 or the older 6101,6100 would be fine, I would run them in an X pattern across the tank.

Something I was not thinking last night, as the 6105s would be plenty of gph for that size tank, is that if you wanted to after getting them you could purchase front suction housings from the 6205s. Doing would give you a broader flow pattern as well.
